摘要
A diode with a reverse rectifying characteristics was fabricated based on the organic heterojunction of copper phthalocyanine (CuPc) and copper-hexadecafluoro-phthalocyanine (F16CuPc). At the heterojunction interface, HOMO of CuPc is bended upwards and LUMO of F16CuPc is bended downwards, since the charge carriers were accumulated at both side of the interface, electrons in F16CuPc and holes in CuPc. The thickness of holes accumulated at the CuPc layer is about 10 nm. which was determined by fabricating organic field-effect transistors with active layers in series of thickness. By utilizing the heterojunction-effect, the threshold voltage in organic transistors can be modified. (C) 2006 Elsevier B.V. All rights reserved.
